U.S. Geological Survey
Saturday, July 8, 2017, 3:41 PM AKDT (Saturday, July 8, 2017, 23:41 UTC)

BOGOSLOF VOLCANO (VNUM #311300)
53°55'38" N 168°2'4" W, Summit Elevation 492 ft (150 m)
Current Volcano Alert Level: WARNING
Current Aviation Color Code: RED

Following the explosive eruption that occurred today at 10:15 AKDT (18:15 UTC) seismicity as detected on neighboring islands has been quiet. The volcanic cloud that was carried to the north and observed in satellite images following the eruption has dissipated and is no longer visible. The SIGMET warning for aviation was cancelled by the NWS at 13:12 AKDT (2112 UTC).

Bogoslof volcano remains at a heightened state of unrest and in an unpredictable condition. Additional explosions producing high-altitude volcanic clouds could occur at any time. Low-level explosive activity that is below our ability to detect in our data sources may be occurring. These low-level explosions could pose a hazard in the immediate vicinity of the volcano.

The Aviation Color Code remains at RED and the Alert Level remains at WARNING.

Status of the ash cloud forecast can be found at the National Weather Service Alaska Aviation Weather Unit website at http://aawu.arh.noaa.gov/
